The Pixel 4's Soli Radar can be enabled in any region thanks to a hidden debug feature

The Google Pixel 4's Soli Radar feature is authorized for use in only certain geographies as it uses the 60 GHz frequency band. Those wanting to use the Motion Sense features can now do so irrespective of the region by taking advantage of a hidden debug feature. However, this requires unlocking the bootloader and enabling root access.

One of the most notable features of the Google Pixel 4 series is the Soli Radar that enables Motion Sense gestures. For Soli Radar functionality to work, you should be using the Pixel 4 in one of the 53 countries where the 60 GHz operating frequency is allowed. While it is understandable why certain regions require disabling the Soli Radar, workarounds have emerged that can enable its functionality irrespective of region. 

Although using the radar functionality is harmless for the most part, do remember that enabling it in unauthorized regions can still be illegal. According to XDA Developers, the app that controls Motion Sense, OsloFeedback, has a hidden debug flag that can enable Motion Sense irrespective of region. 

To do this, the Pixel 4 must be bootloader-unlocked and rooted with Magisk. Once that is done, simply enter the following adb commands to enable Motion Sense:

adb shell setprop pixel.oslo.allowed_override true 

The above command is valid for the current session. For the functionality to persist between restarts, use

adb shell “setprop persist.pixel.oslo.allowed_override true; setprop ctl.restart zygote”

You can also use Xposed along with Riru-Core and EdXposed to enable Soli Radar functionality in any region. Just search for "EnableSoliOnPixel4" in the Xposed Manager and install it.
